Method

Boil potatoes in salted water for 10 mins. Start with cold water and bring to the boil.
Fry onion and sausage in a frypan until golden. Don’t let the onion brown. Cook the Chorizo so the fat renders out, but try to prevent the bottom of the pan going dark. Cook it low and slow, but not too low. It has to render but not brown too much.
Once it turns golden, Add garlic and chilli then add potatoes, beans, tomatos, bay leaves, stock
bring to boil and simmer for 10 mins
